"Could not register trial, this account had been registered to a trial before" error
If during the setup of the CPM instance you receive the following error after step 5:
Failed registering account. Reason: Could not register trial, this account had been registered to a trial before, please contact N2WS support
Please choose "This account is already licensed" in step 2 instead of "I'm starting a free trial".
If you receive the "Configuration failed" error after that, please terminate this instance, launch a new one and perform the configuration choosing "This account is already licensed" in step 2.
